Description

The getprofattr() and getprofnam() functions each return a prof_attr entry. Entries can
come from any of the sources specified in the nsswitch.conf(4) file.

The getprofattr() function enumerates prof_attr entries. The getprofnam() function searches for a
prof_attr entry with a given name. Successive calls to these functions return
either successive prof_attr entries or NULL.

The internal representation of a prof_attr entry is a profattr_t structure defined
in <prof_attr.h> with the following members:

The free_profattr() function releases memory allocated by the getprofattr() and getprofnam() functions.

The setprofattr() function “rewinds” to the beginning of the enumeration of prof_attr
entries. Calls to getprofnam() can leave the enumeration in an indeterminate state.
Therefore, setprofattr() should be called before the first call to getprofattr().

The endprofattr() function may be called to indicate that prof_attr processing is
complete; the system may then close any open prof_attr file, deallocate storage,
and so forth.

The getproflist() function searches for the list of sub-profiles found in the
given profname and allocates memory to store this list in proflist. The
given profname will be included in the list of sub-profiles. The profcnt argument
indicates the number of items currently valid in proflist. Memory allocated by
getproflist() should be freed using the free_proflist() function.

The free_proflist() function frees memory allocated by the getproflist() function. The
profcnt argument specifies the number of items to free from the proflist
argument.

Return Values

The getprofattr() function returns a pointer to a profattr_t if it successfully
enumerates an entry; otherwise it returns NULL, indicating the end of the
enumeration.

The getprofnam() function returns a pointer to a profattr_t if it successfully
locates the requested entry; otherwise it returns NULL.

Usage

Individual attributes in the prof_attr_t structure can be referred to by calling
the kva_match(3SECDB) function.

Because the list of legal keys is likely to expand, any code
must be written to ignore unknown key-value pairs without error.

The getprofattr() and getprofnam() functions both allocate memory for the pointers they
return. This memory should be deallocated with the free_profattr() function.
